I am student in Hiroshima University. I want to calculate ATP content in some cultured sample using AF-70 ATP Tester. Now the problem is I never used this instrument and I don't have the manual for this product. However, I tried to prepare the solution from Japanese material provided with the ket used for this instrument. While I tried to calibrate/calculate the ATP in my required sample I couldn't get values. I don't know how to use this instrument, if anyone is using this product can you please guide me?? I will be highly obliged for your kind support.
